Title: Method for cleaning ultraviolet radiation pasteurizer
Inventor: HIRASAWA IZUMI
IPC: C02F1/32
Filed: 1987-11-20
Abstract: PURPOSE:To prevent decrease in radiation rates, by passing a fluid containing fine solid particles through a passage for liquid to be treated at a velocity larger than the settling velocity of said solid particles. CONSTITUTION:Secondary sewage to be treated 2 flows in through an inlet pipe 4 and then passes through a passage 9, during which ultraviolet rays are applied to said sewage by means of an ultraviolet lamp 5 through a protector tube 6 to effect pasteurization, and then said sewage is discharged from a discharge pipe 8. As time passes after the introduction of the sewage, slime is formed over the protector tube 6, causing the radiation rate to fall. In this instance, the flow of the sewage is stopped and slurry suspended with silica sands having a diameter 0.1-0.2mm is fed for a predetermined period from a slurry injection port 3 provided on the inlet pipe to clean the surface of the protector tube. In this manner, efficient cleaning can be conducted.

IPC: H03K19/0175
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit that relaxes a high voltage fed to an input buffer. SOLUTION: A voltage of a Vin-(Vref1+Vth (MP2)) or over is not applied to an oxide film between a gate and a drain of a 1st MOS transistor (TR) MP1, where Vth(MP2) is a threshold voltage of a 2nd MOS TR MP2. Even when an input signal Vin fed to a terminal 8 is increased in excess of a specified high level, a voltage applied to the oxide film between the gate and the drain of the 1st MOS transistor(TR) MP1 is relaxed. Furthermore, a higher voltage of a Vdd2-Vth(NM4) or over is not applied to a gate electrode of a 3rd MOS TR MN3, where Vth(MN4) is the threshold voltage of a 4th MOS TR MN4. Even when the high level of the input signal exceeds a regular power supply voltage, the voltage applied to the gate oxide film of the 3rd MOS TR MN3 is relaxed.

Inventor: HAGIWARA TOMOE
IPC: G01N27/74
Filed: 1994-11-02
Abstract: PURPOSE:To obtain a method and a device by which a stable measured value of the toner concn. is obtd. by controlling the center line average roughness of the surface of a magnetic bridge system concn. sensor to a specified value or smaller. CONSTITUTION:The center line average roughness of the sensor surface of a measuring device to detect the magnetic permeability of a developer with the magnetic bridge system concn. sensor and to measure the toner concn. is specified to <=0.4mumRa.

This makes the initial state of the sensor output unstable and the desired value is not obtd. Therefore, in the developing zone of a copy machine using a two-component developer, a stable measured value of the toner concn. is obtd. by the method and the device to measure the toner concn. using a magnetic bridge system concn. sensor having <=0.4mumRa center line average roughness of the sensor surface.

Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a method by which transmission lines can be re-stringed inexpensively in a short time without numerous dangerous works on a steel towers. SOLUTION: In a method for re-stringing overhead transmission line, the uppermost upper-phase transmission line of three-phase transmission lines stringed between steel towers is re-stringed by utilizing an existing line 1 and the lowermost lower-phase transmission line is re-stringed by using a sag suppressing aluminum conductor steel reinforced 3 which can exhibit such a large sag suppressing effect that can secure a sufficient separating vertical distance from a ground structure 8.

CONSTITUTION:A P-type anode region 3 is formed to an N-type semiconductor layer 2 shaped to the surface of a P-type semiconductor substrate 1 through selective diffusion, etc. N-type high concentration regions 4a, 4b are shaped simultaneously to the surfaces of the P-type anode region 3 and the adjacent N-type semiconductor layer 2 by utilizing a deep N-type diffusion technique such as contact diffusion. An N-type impurity is implanted to a polycrystalline semiconductor layer 6 through ion implantation, etc., at the same time as the formation of an emitter for a transistor, and an N-type cathode contact region 5 is formed into the N-type cathode leading-out region 4b, and employed as a cathode for a constant voltage diode. An anode is led out of the P-type anode region 3. Accordingly, since the high-concentration N-type cathode contact region 5 is not shaped onto the high-concentration P-type anode region, crystal defects are difficult to be generated, and crystal defects have no effect on a junction section in the constant voltage diode even when they are generated.
